'y 'l LOCOMOTIVE'I S'JZACK"A To' all whom# may/concern la` citizen of theUnited States, and a resident. of` Greenwich, inthe county of Fair-- fieldamlState of Gonnecticutghave invented a: certainA new andA usefullmprovement in Locomotive Stacks, of. which improvement the following'ris a. specification.

invention relates to-sm ke stacks-for locomotive engines, andl isl an improvement United States, No. 1,239,370,- werey granted and' issued toVilliam Elmer, under ,date

of' ySl'eptember 4,1917.v The object off my invention is to provide means, of simple type set. lforth in said Letters .Patent No. 1,239,370,maybe accurately assembled, and

securely maintained, in.. proper relation, andV means for supporting a smoke stack, of such type in operative position, withthe Vcapacity Vof ready removal` .and replacement, when desired, andlwitho'ut interfering Vwith the location. of. adjacent members in the 'locomotive smoke box.

in vertical planes, symmetrically about its axial line. The discharge channels, which are preferably wrought metal tubes, are assembled in proper relative positions, by being inserted, at their ends, .in guiding lugs .n an upper head plate, 2,fand a lower head plate, 2a, said guiding lugs being formed at the inner ends of openingsn in the head plates, rwhich openings are of the same diameter, in the upper head plate, as that of the inside ofthe discharge channels, and are preferably, as shown, outwardly tiared or tapered, inthe lower head plate. When so assembled, the discharge channels and the Application fnedirprn 4, 1925,-Y seria1-:No..V2o,-e23f.

descriptively' to the specific embodiment The exhaust pipe, 6, passesthrough the table plate, 8, connected to the diaphragm, 9, in the usual manner, and a sheet of netting, 10, extends upwardly and forwardly' from the table plate to the wall of the smoke l box. The'discharge of steam from the exhaust pipe is effected, through a plurality of nozzles, formed integral-with connecting ribs, 6b, and bolted to the exhaust pipe, eachv desired, without interference withlthe ready.` lremoval of the nozzles independently ofthe supporting bolts, vby a' plurality of vertical ico."
